INTRODUCTION 1._Background Information For thousands of years human beings have been fighting in battles‚ always trying to find new ways of killing each other and winning. Combat was getting more and more sophisticated and human force was not sufficient enough to conquer a castle or destroy a ship. That was the time when ancient engineers introduced siege warfare‚ when “simple yet complicated hurling machines that rely on the fundamentals of math and physics using levers‚ force torsion‚ tension

Individuals love to go to the amusement parks and try out the rides that are available. The most common and thrilling ride is the roller coaster. An amusement park is not an amusement park if it does not contain a roller coaster. What makes these roller coasters so fun that every amuse parks has one. A lot of people would say it is their extreme high speeds that makes it very exciting. That is a valid answer‚ but it is the wrong answer. The speed has nothing to do with the excitement. It is more

We can relate physics to softball in many different ways. It is actually hard to not think about the game of softball without some physics in mind. Specifically‚ the ideas of momentum and energy helps define the way softball works and why it works. Momentum Running: When running the bases in softball‚ there is a lot more to it then the average person would think. While we run the bases‚ we are changing our momentum by applying more force‚ the force of friction‚ onto the ground which causes more

Physics Investigation A Formula 1 Margarine Tub Aim: I am going to investigate how the mass of a margarine tub affects the distance it can travel. The following Factors will affect the distance the tub can travel: · Surface area of the tub · Air Resistance · Force applied to propel tub · Length of elastic bands used to propel tub · Surface on which tub will travel Prediction I predict that as the mass of the tub increases‚ the distance the tub can travel will decrease. This

How Guns Work A gun is a weapon that uses the force of an explosive propellant to project a missile. Guns or firearms are classified by the diameter of the barrel opening. This is known as the calibre of the gun. Anything with a calibre up to and including . 60 calibre(0.6 inches) is known as a firearm. The precise origin of the gun is unknown‚ although they were in use by the early 14th century and were common place in Europe by mid-century. These early guns were nothing more than large

Newton’s Second Law (Predicting Accelerations) Abstract: The purpose of this experiment is to study the Newton’s second law and the behavior of objects for which all forces are not balanced. In this experiment‚ a small mass m will be connected to the dynamics cart by a string. The string will pass over a pulley at the table’s edge so that as the mass falls the cart will be accelerated over the table’s force. The cart will be released from rest and allowed to accelerate over a distance. Using a

Why and What I hope to achieve: I believe that the purpose of doing this is to allow me to demonstrate my understanding of Elastic potential energy. And the projectile concepts of the effect of changing potential into kinetic energy and for me to demonstrate my ability to apply elastic potential energy to a scientific investigation. What am I going to do and what will it prove: I am going to use an elastic band and release it from different tensions I will then measure how far it ‘flies’

The object of ball bearings (and roller bearings) is the substitution of pure rolling motion for plain sliding friction. <br> <br>Ball Bearings rely on the rolling motion of hardened steel balls to absorb loads. This rolling motion produces far less friction than the sliding motion. These steel balls are held in circular rows between an outer and inner ring‚ which have raceways‚ or slots‚ grooved into them to guide the balls. Ball bearings are available in both filling-slot and no filling-slot types

KINEMATICS 1. An object is moving with uniform accleration. Its velocity after 5 sec is 25m/s and after 8 sec‚it is 34 m/s. Find the distance travelled by this object in 12th second. Ans. 44.5 A particle starts with a velocity of 100 cm/s and moves with –2 cm/s2 acceleration. When its velocity be zero and how far will it have gone? Ans. 50s ‚ 25m m/s. After 7 a time interval ∆t‚ the velocity of the body is reduced by half‚ and after the same time interval‚ the velocity is again reduced by half

Purpose The purpose of this experiment is to test Coulomb’s Law which states that the force between two spherically symmetric charged objects is directly proportional to the product of the charges‚ and inversely proportional to the square of the distance between the centers of the two charges. In mathematical vector notation Coulomb’s Law is expressed as where Fr is the force on particle 1 due to particle 2 in Newtons‚ q is the charge on 12 1 particle 1 in Coulombs‚ q2 is the charge on particle
